Call for Demos

Important Dates

Submission Due August 02, 2024 (11:59 p.m., anywhere on earth)
Notifications August 09, 2024
Camera-Ready Deadline August 16, 2024

We invite you to showcase implementations of novel and compelling interaction concepts, techniques, devices and systems. We particularly encourage highly interactive demos and creative experiences, ranging from novel wearables, web systems, prototype devices and commercial products, to XR and large interactive installations. All topics that are directly or indirectly relevant to spatial user interactions and interfaces are welcome. This year we will also be seeking research prototypes to respond to current challenges in HCI and XR, related to spatial interactions, input and output, as well as creative experiences combining novel multi-sensing and -modal techniques and/or volumetric, 3D data.

Please submit an abstract (max. 2 pages) describing your demo as well as supporting materials (see Submission Instructions below).

All demo submissions go through a peer-reviewing process. The demo chairs will announce recommendations for presentation formats, logistics and provide early access for technical setup before the conference. For questions please email the demo chairs at

Submission Instructions

  • Camera-ready abstract: Submit a two-page manuscript formatted in the ACM SIG Proceedings format. Submission will be made through the PCS system. Unlike paper submissions, demo submissions are not anonymous. Be sure to include the names and affiliations of all authors.We strongly encourage that the abstract is submitted in camera-ready format.
  • Walk-through video: Every submission should be accompanied by a short video of the demo (up to 2 minutes, max 50MB). Submitted videos can be provided in QuickTime, MPEG, or Windows Media Viewer format. If in doubt, use MPEG-4 format with an H264 encoder for video and an AAC encoder for audio. The videos may be used for promotional use.
  • Supporting material and needs: Demos should be completed and presentable in a conference setting. The submission should include a supporting file with information about:
    • the overall architecture of the system, installation, network connectivity, exhibit or performance, the planned interaction with the audience.
    • a floorplan/schematic and/or short paragraph with a brief description of the layout (showing components such as projectors/cameras) of the demo and a picture showing the demo in action.
    • an equipment list you will be bringing and the ones you will be requesting. Please note that standard equipment will be provided(space, a table/standing board, power), but any other requested equipment is not guaranteed.
    • additional needs in terms of internet, lighting, area etc. Please note that the distribution of space for selected demos will be allocated equitably and tailored to accommodate the specific needs of each demo. Space arrangements will be determined based on the requirements and nature of the demos submitted.
    This information is required in the supporting file, even if some of it duplicates what is provided in the camera-ready abstract.
  • Submissions are expected to address topics within the scope of SUI. Unlisted but strongly related topics are also welcome.
  • At least one author of each accepted demo will be required to register by the early registration deadline to present at the symposium. The author is also required to be available during the demo sessions.


Submissions will be peer-reviewed. Abstracts of accepted demos will be archived in the ACM Digital Library, and be provided as open-access for the first month following the symposium. Please note that at least one author of each accepted work will be required to register to present at the symposium. If no author is registered by the early registration deadline, the accepted work will be withdrawn from the proceedings and digital libraries.

Please be informed of the following messages from ACM:

  • By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policies, including ACM's new Publications Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy.
  • Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper. ACM has been involved in ORCID from the start and we have recently made a commitment to collect ORCID IDs from all of our published authors. We are committed to improve author discoverability, ensure proper attribution and contribute to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.
